ATLAS CRAFTSMAN 10 & 12" Lathe slow feed half speed Nylon Gear

This fine Nylon gear has improved design for better durability and performance
 It is superior to other plastics 3D printed replacements
Nylon is a first choice gear material - it won't create plastic dust as ABC does!

3D printed out of Nylon - tough and flexible plastic
Nylon naturally slippery, no lubrication required!
Runs quieter and smoother 

Only Nylons should be used for gears where a slippery surface is desired.
  All other materials (PLA, ABS, PET, etc.) will grind creating a plastic dust and eventually fail!

With 12 inch Craftsman / Atlas lathe shown on the last image.
The compound 48 / 24 gear in place, you lose the "slide" capability.
There is no "A-IN" position so you lose not just the top row of threads but the top two rows.
The largest thread you can cut without moving anything around is 16 t.p.i.
